The value of a Hobby

Life is generally busy. Between home and work, and the all the maintenance that goes into keeping life running, there isn’t much time for anything else. Until you make some.

Over the past 6-8 weeks most of us have been under lockdown or ‘shelter in place’. During this time, many have asked me what I do or how I spend my time. The fact is that I really have had no time to ‘spend’. It has been busier than ever and as always, when I have any spare time, I just route towards doing things that matter to me.

On the other hand, even when life is routine. I ensure I make it a point to dedicate my time to those things that define me, make me who I am, grow as an individual.

There are 1440 minutes in a day, times 7 days, times 52 weeks. It is hardly possible that we can’t find the time to do the things we want to do. The question is never about time. There is always enough time for everything. Talk to people who speak about the quantum realm and they will be first to point out that time will warp to allow one to do the things they are passionate about.

For many, perhaps I should say most, the hardest thing is to know what they would like to spend their time on. Before we can be passionate about anything, one has to know oneself.

What do I like to do? What would I like to spend my time on? what do I want to create? What impact do i want to leave behind? What do i want to be known for when i am done? What problems do i want to solve? Who can i help? Who can i serve?

Most people go about life living through the drudgery of tasks and when they look at others doing things that matter to them, it appears like those people are blessed. The fact is that those people are neither anymore blessed than us, nor are they gifted with any more skills that we have. The fact is that those individuals have identified one or more things they are truly passionate about and they pursue it relentlessly.

In simple terms, some of these ‘things’ are known as hobbies. they are different from interests. They are not pastimes. Hobbies involve deep engagement, a form of ‘doing’.

I consider myself very blessed to have had a passion for aviation. This passion has led to various related hobbies and I have more than one. Model aircraft building, drone flying, simulator construction, real world flight, aviation photography and videography, composing guitar solos to mirror the sentiments that aviation produces. These keep me grounded and level-headed. Working on my hobbies brings in a focus, keeps the mind engaged, provides a sense of calm, generates immense gratification, and increases creativity exponentially.

One of the questions that i get asked when someone sees my work is how did i begin. I don’t think there is a single day when a hobby becomes a part of one’s life. Most of my hobbies came in naturally. They grow on me. Aviation has been a passion since my childhood. Music has been with me since my high school days. I was building transistor radios when i was 12. So most of my hobbies have stayed with me since i was little. Indeed with time, the size and scale of my hobbies have grown much. Where I would build a small scale model aircraft, I am now inspired the next larger one. Where i used to have one certificate to fly, I am now inspired to pursue the next block of learning and get the next certificate. Where a couple of decades ago, I was only interested in finding out how to eliminate the keyboard and replace real switches and knobs into a flight simulator, I started on building a scale size flight simulator. It turned into a 20+ year project and to this day gives me immense satisfaction. I call it it my life’s work.

Yes, hobbies can lead to life size work. There is always something to do. Replace the engine on a model aircraft, try a new propeller to test for efficiency, build a foam plane with electric propulsion. Fly to a new non-towered airfield in the real-world. Plan a project to fly to the sand dunes at Kitty Hawk where the first powered flight occurred. On the simulator side, update navigation data, upgrade the software, add a new aircraft, or fine tune performance. If all this is finished, sit by a small airfield and do some plane spotting, or curate some aviation pictures. When this done, come back to composing a new solo in A minor to mirror the feelings of being in the air. There is no end of the avenues that hobbies open up.

The hardest for many is to identify what they are really interested in. The best way to get past this point is to try a few things. Its easy to gravitate to one or more things if we try them, It’s also important to separate out pass-times from hobbies. Hobbies are most likely things to do. Pass-times are meant to pass one’s time. Rest assured that having a hobby will leave very little time to pass.

A hobby can be in any field or realm. Tending a garden, collecting stamps, curating pictures of building architecture, sewing, knitting. cooking, painting, woodcraft, restoring a vintage car or plane, curating artifacts for a museum.., there is no end to the various things that one can do with time.

At few points in our past would having a hobby be as immensely valuable as it has been over the past two to three months with the COVID-19 situation.

In the spirit of not leaving the sight of a goal without taking a step towards it, let’s begin!
Let your creativity blossom.

Simulators during the lock-down

I write frequently about the value of flight simulators. There couldn’t be a more important time than we are in now to realize the value of a simulator.

It has something for anyone connected to aviation. For students, a simulator provides a great platform to stay proficient. For pilots, it provides the basis to avoid rust and at the same time enjoy flying while not being able to access the real aircraft and fly anywhere. For instrument rated pilots or students, it provides the opportunity to practice approaches of various types. The benefits of simulation have been long discussed here in my blog and everywhere else.

I would urge anyone with access to a simulator to use them extensively. Whether you an log the time in your logbook or not is not material. Whether you can seek credit for the time or not is not material either. Whats important is that you can use the simulator. The transfer of training benefits from a simulator are significant. If you are able to use a networked simulator with a service like PilotEdge, these benefits are further enhanced.

Building a Motion Platform – the basics

For many years now, building a motion platform for a recreational flight simulator has been on my mind. Extending a home-built recreational simulator with a motion seat or motion base is nice science project but is also a meaningful extension to the study of the simulators. Three years ago I had built a small servo-based model of a motion platform with 2 degrees of freedom (2DOF).

Three weekends ago, I started down the path of figuring out a design to make a scale version of a motion platform.

There are several parts to the development of a motion platform that can connect to a PC-based simulation engine. I have had very little experience with any of these steps and so it had to be learning by doing.

The overall set of steps are as follows –

  • Determining how to communicate with a real servo or motor or actuator 
  • Determining whether to use motors, servos or actuators
  • Validating the hardware cards that could interface between a PC and those motors or actuators
  • Writing code to drive those cards that drive those actuators or motors.
  • Powering actuators or motors or servos
  • identifying the right actuators or motors or servos that will serve the platform build
  • Connecting the actuators to the interface cards and then to the PC
  • Writing test code that tests the actuators
  • Connecting the game to simulation platform engine
  • Connecting the platform engine to hardware driver engine
  • Acquiring and transmitting telemetry to the chain above so as to be able to get the game’s motion to reflect realistically on the actuators.

Note that none of the above yet even discusses the build of a platform base or seat. This is just the work that is needed to get the concept validated.

For the simple prototype I chose to go with Progressive Automation for actuators. I also chose to go with MultiMoto Motor/Actuator driver. This card would seamlessly integrate with an Arduino chip. I picked up the LA-14P actuator from Progressive because it had built-in feedback. Needed a power supply and used my 10 Amp, 12V power supply that I use to charge my RC airplane batteries.

Until next time…

Role of Simulators in FAA’s NextGen program

Simulation ecosystems are used in a variety of applications beyond their use in training of pilots. While simulators were initially used to help train pilots, they rapidly evolved into playing important roles in advancing aviation overall. Human factors assessments, aircraft and airport design, flightdeck instrumentation design, operating procedure development, air traffic control training, air traffic flow management evaluations are some examples of where simulators are used outside of the realm of direct pilot training (Lee, 2005).

A specific current day example of the use of simulators outside of pilot training is in FAA’s NextGen Program. Air traffic is expected to increase over the next 15 to 20 years and the “NextGen” Program is a comprehensive overhaul of the US National Airspace System to respond to the upcoming demands. NextGen introduces revolutionary new approaches to capacity problems. It will use newer technologies and automation to shift the way air traffic is managed. NextGen is not one idea, but a series of initiatives aimed at transforming different aspects of the aviation ecosystem (Federal Aviation Administration, 2014). The program has been structured into a set of program areas, typically focused on laying out infrastructure. These areas include Automatic Dependent Surveillance Broadcast (ADS-B), En Route Automation Modernization (ERAM), Data Communications (DataComm), National Airspace System Voice System (NASVS), Terminal Automation Modernization and Replacement (TAMR), and System Wide Information Management (SWIM). NextGen also has a set of portfolios that deliver new capabilities. The portfolios are Time-based Flow Management, Collaborative Air Traffic Management, Improved Approaches and Low-Visibility Operations, Improved Surface Operations, On-Demand NAS Information, Performance-based Navigation, Improved Multiple Runway Operations, Separation Management, and Environment & Energy (Federal Aviation Administration, 2014).

Clearly, the NextGen program will advance commercial aviation in the US and serve as a role model for other such implementations. It will also require changes that could impact the design of future aircraft, air traffic control processes and devices, airport layouts and maintenance facilities, training content, training processes, job aids and performance support systems. The NextGen program will rely heavily on the use of simulation environments to design and test the necessary changes (Callantine, 2008; Crutchfield, 2011; Doucet, 2013; Hunter, 2009). Many of the proposed changes need to be tested before implementation begins, but it is difficult to conduct human factors tests on an environment that does not yet exist. The use of synthetic environments in these situations bring benefits in terms of cost and risk. There is significant benefit to being able to simulate scenarios and test out human interaction with machines before their use in real-world environments.

One very specific example is the use of NextSim. NextSim is an ATC research simulator that collects performance, workload, and situation awareness data to address human factors/ ergonomics issues that might arise in NextGen (Durso, Stearman, & Robertson, 2015). Another example is where, according to a Rockwell Collins’ release, a Boeing 737 flight simulator in the FAA’s Flight Operations Simulation Laboratory (FOSL) in Oklahoma City, will be used to study the viability for NextGen to safely achieve benefits such as lower landing minima by using Rockwell Collins head-up displays with synthetic and enhanced vision during different phases of flight in low visibility conditions (“FAA chooses Rockwell Collins’ guidance systems”, 2012). At Oshkosh AirVenture 2010, the FAA NextGen Data Communications (DataComm) program demonstrated by using simulators that new Data Comm technology will deliver major savings in time, money, fuel, as well as, environmental effects. The technologies introduced by DataComm included its new air traffic control (ATC) and Boeing 737 cockpit simulators (Gonda & Zillinger, 2010).

Callantine (2008) describes the use of simulation to analyze human-in-the-loop route structure simulation data. Hunter (2009) describes the design and test of the simulators for use in NextGen, and further proposes test protocols for NextGen simulators. Doucett (2013) details out a cross-organization effort to setup a distributed environment comprised of aircraft and ATC simulator that can serve as a collaboration tool for NextGen design and test. Prevot, Homola, and Mercer (2008) study the trajectory based operations, a NextGen component using simulators.

Based on the discussion above, there is little doubt that simulators and synthetic environments have, and continue to play, a critical role in aviation, over and beyond their use for direct pilot training.

Virtual Reality & the Oculus Rift

Its here… the new standard for Virtual Reality. The #OculusRift is finally ready for use and deliveries have been announced for Q1 2016. Virtual Reality has looked for traction for many years. The Rift will change everything we have known till date about #VR. As a simulator hobbyist who has spent years trying triple monitors, triple channel projection, FOV calculations I can clearly see – no pun intended – the value of the Rift. In the mad pursuit of achieving high resolution immersive 210 degree wrap-around views I had at one point 9 monitors dedicated to such wrap around view generation – and yet, the views would still feel like you were watching a monitor.

The Rift changes all that. Watch one of the videos I found on Youtube, you will see what I am talking about.

Simulators – Motion Platforms

For many years now, the concept of having a motion platform for hobby simulators has been on my mind. A couple of months ago, I began on this journey. Of course I didnt want to dive into building a full-scale one right away. I thought a prototype would be a good idea.

The video below shows my first gen prototype in action. A lot more work to do, however the basic concept has begun to take shape.
